I don't recall exact figures, but for MY2006, the last year of both cars, it was roughly:

$37,600 for the 330ci
$48,600 for the M3

IOW, the M3 was $11,000 or about 30% more than the 330ci. The 335i is about $41,000 so unless the new M3 is only about $53,000 (not very likely) it will command a higher preminum percentage-wise than the old one did.
